Dailey, a 23-year-old Boston Architectural College graduate student, has been missing since Oct. 2.

The Massachusetts State Police Department said the latest body was spotted by a Boston University rowing coach at about 7:25 a.m.

According to the Suffolk County District Attorney's office, the remains recovered were positively identified after a review late Tuesday of Dailey’s dental records by forensic odontologists.

The facts and circumstances surrounding Mr. Dailey’s death remain under investigation by State Police. "We rule out no possibility and we promise Mr. Dailey’s family a thorough, comprehensive search for the truth as we investigate his death," the District Attorney's office said.

Reports from the scene said a cinder block was tied to Dailey's body.

During the weekend, desperate family and friends turned to social media and celebrities to help find Dailey.

His roommate launched the campaign, believing there is power in numbers.

"We are trying to contact Boston athletes and celebrities, like Mark Wahlberg, and tweet at them," said Rachel Erulkar, Dailey's friend.

"It's knocking on the door of 10,000," said Miles Smith, Dailey's roommate.
